The main purpose of commercial HVAC systems is to provide you as well as your employees with a comfortable place to work by chilling the air inside the commercial premises during the summer and heating it during the winter. Although these systems are relatively complex compared to domestic HVAC systems, having a better understanding of how they work will help you in case anything goes wrong.
WARNING: All of these units contain condensers and other electronic parts that store electricity even after switching off the power. Therefore, you should never attempt to fix it by yourself.
How do commercial HVAC systems work?
The different types of systems
Having knowledge about the different types of systems can help you make an educated decision and choose a system suitable for cooling or heating the volume of air within your commercial complex.
These systems are available in three different variants:
• Single split
• Multiple split, and
• VRV or VRF
This affordable system is suitable for the majority of small commercial buildings. They are perfect for buildings containing small offices, restaurants, shops, and server rooms, etc. Their advantage is that they allow for cooling and heating of individual rooms. They can work in tandem to cool larger spaces too. The system consists of a compressor, a thermostat, and an evaporator coil containing refrigerant that cools the air passing over the coils. The chilled air is then circulated throughout the building through ducts. You can control the temperature by adjusting the thermostat setting via remote control.
These units differ from the single split systems as you can connect up to nine indoor units to a single outdoor compressor. Their compressors operate at variable speeds, because of the inverter technology used. The forced air system of single split systems consumes a large amount of energy each time its compressor switches on. This process is repeated multiple times during the day. The inverter technology contains tiny sensors that detect small temperature changes and make necessary adjustments as and when required.
VRV and VRF systems
Both names refer to the same technology with the sole difference that Daikin holds trademark rights on one of them. These systems are perfect for hotels, large office spaces, retail complexes, and large residential buildings. These systems are available in two variants: heat recovery and heat pump. The latter system, which can cool or heat the air inside a building is ideal for open plan areas. The former is perfect for buildings that have numerous smaller rooms. These systems gather unused heat from different parts of a building as use it to heat water and the air inside other rooms.
